Concrete bridge deck self-repairing drainage pavement structure and construction method thereof
The invention belongs to the technical field of bridge deck pavement, and particularly relates to a concrete bridge deck self-repairing drainage pavement structure and a construction method thereof.The concrete bridge deck self-repairing drainage pavement structure is technically characterized in that the pavement structure sequentially comprises a cement concrete slab base layer, a wet bonding resin layer, a self-repairing porous concrete pavement layer, a high-temperature reaction type bonding layer and a self-repairing PA-10 pavement layer from bottom to top; wherein the materials of the self-repairing porous concrete pavement layer comprise concrete ingredients and bacterium-carrying ceramsite; the bacterium-loaded ceramsite is prepared by carrying out carbonization modification on ceramsite and then loading bacillus. The ceramsite pre-loaded with microorganisms is doped into a porous cement concrete structure, so that the cracking disease self-repairing function is achieved, the upper-layer large-gap self-repairing PA-10 structure is combined, the requirements of microorganisms for air and moisture are met, the microorganism self-repairing effect depth is effectively improved, and the cracking disease self-repairing effect is improved. And meanwhile, the synergistic consistency of drainage and self-repairing functions of the upper and lower surface layers is realized.
本发明属于桥面铺装技术领域，具体涉及一种混凝土桥面自修复排水铺装结构及其施工方法，其技术要点如下：铺装结构从下到上，依次包括：水泥混凝土板基层，湿粘结树脂层，自修复多孔混凝土铺装层，高温反应式粘结层，自修复PA‑10铺装层；其中，自修复多孔混凝土铺装层的材料包括混凝土配料和载菌陶粒；载菌陶粒是由陶粒经碳化改性后，负载芽孢杆菌制备而成。本发在多孔水泥混凝土结构中掺加预负载微生物的陶粒，以实现开裂病害自修复功能，结合上层大空隙自修复PA‑10结构，以满足微生物所需空气和水分需求，有效提升微生物自修复作用深度，同时实现上下面层排水与自修复功能的协同一致性。
